Patent Document 1 describes how an alarm device issues a warning depending on the level of wastewater, and Patent Document 2 describes how a request to have the waste removed is output when the amount of waste exceeds a set value.

However, collection companies for liquids (excrement) such as feces and urine collect liquids upon contact from managers of temporary toilets at construction sites, etc., but there are cases where they have to go to the same direction to collect liquids for two consecutive days, for example. When they have to go in the same direction or in the same area to collect liquids, there is a problem that collection efficiency is low.

In particular, gasoline prices have risen sharply in recent years, and when waste collection companies must repeatedly make collection trips to collection points far from the company in the same direction or in the same area at the same time, there is a problem of wasting energy, such as gasoline, in addition to the efficiency of collection.

These problems are not limited to the collection of excrement and other waste materials, but also occur when collecting waste oil, waste cooking oil, waste liquids, wastewater, and sludge.

The objective of the present invention is to improve the efficiency of liquid recovery.

Another object of the present invention is to reduce the energy used for transportation.

A liquid recovery system according to a first aspect of the present invention is a liquid recovery system for recovering liquid having a detection device that detects an amount of liquid, comprising:
the liquid recovery system includes a terminal and a server capable of communicating with the detection device;
The server,
A communication unit capable of communicating with the terminal and the detection device;
a mapping unit that displays the liquid amount information received from the detection device on a map displayed on the terminal;
a calendar unit that displays the liquid amount information received from the detection device on a calendar displayed on the terminal;
A storage unit that stores liquid amount information, map information, and customer information;
and a control unit that predicts how the liquid will increase from the change in the amount of liquid detected by the detection device.

The control unit predicts how the liquid will increase from changes in the amount of liquid in the container and calculates the estimated date when the liquid will reach the container's maximum capacity.

The control unit also predicts how the liquid will increase based on changes in the amount of liquid in the container, and calculates an estimate of the future amount of liquid (estimated amount).

In other words, this invention provides an estimated date when the liquid will reach the maximum capacity of the container.

Therefore, collection groups can be set up to collect liquid from collection areas in the same direction or in the same area with close estimated dates, improving collection efficiency and saving energy required for travel.

The liquid may contain impurities and may be viscous.

A liquid recovery system according to a second aspect of the present invention is the liquid recovery system according to the first aspect,
the control unit calculates an average daily amount of accumulated liquid by dividing a sum of amounts of liquid detected in the past by a corresponding number of days based on information on the amount of liquid detected by the detection device stored in the memory unit;
This liquid recovery system calculates the number of remaining days by dividing the difference between the maximum allowable amount of the container and the amount of liquid by the average value.

For example, the sum of the amount of liquid detected over a 90 day period is divided by the number of days, 90, to find the average amount of liquid per day.

In other words, if the amount of liquid in the container is 1800L, divide 1800L by 90 days to find that the average amount of liquid per day is 20L.

If the maximum capacity of the container is 1000L and the amount of liquid in the container is 800L, the quotient of 10, obtained by subtracting 800L from 1000L (200L) and dividing that difference by the average value of 20L, is the number of days remaining.

Knowing the number of days remaining allows you to calculate the estimated date when the liquid will reach the maximum capacity of the container.

For example, this will allow users to know the deadline for when liquid waste such as feces and urine from temporary toilets must be removed (collected), and they can prioritize the removal (collection) of temporary toilets whose removal deadline is approaching.

Also, knowing the estimated date when the liquid will reach the container's maximum capacity allows collection groups to be set up to increase collection efficiency.

In other words, collection groups can be set up to collect liquid from sites in the same direction or in the same area with close estimated dates, improving collection efficiency and saving energy required for travel.

A liquid recovery system according to a third aspect of the present invention is the liquid recovery system according to the second aspect,
the calendar unit has an amount prediction calendar that displays an amount of liquid on the terminal,
The liquid recovery system includes a volume forecast calendar that displays an estimated date when the liquid will reach the maximum capacity of the container.

Collection groups can be set up to collect liquid from sites in the same direction or in the same area with close estimated dates, improving collection efficiency and saving energy required for travel.

A liquid recovery system according to a fourth aspect of the present invention is the liquid recovery system according to the third aspect,
The calendar unit is a liquid recovery system that sets a threshold value for the amount of liquid detected by the detection device, and changes the color of the customer information displayed on the amount prediction calendar as the estimated date when the liquid will reach the maximum allowable amount of the container when the amount exceeds the threshold.

In this embodiment, a two-stage threshold is set, and the color of the customer information tag displayed changes from blue to yellow and from yellow to red.

The color of the customer information displayed on the volume forecast calendar changes, so you can see at a glance which sites need to be prioritized for collection.

A liquid recovery system according to a fifth aspect of the present invention is the liquid recovery system according to the first to fourth aspects,
This is a liquid recovery system, wherein the liquid is excrement such as feces and urine, waste oil, waste edible oil, waste liquid, sewage, or sludge.

The present invention can be used, for example, to collect (recover) excrement such as feces and urine, collect waste oil, collect waste edible oil, collect waste liquid, collect wastewater, collect sludge, etc.

A control process is performed to predict how the liquid will increase from the change in the amount of liquid detected by the detection device.

Such a program would achieve the same effect as the liquid recovery system of the first aspect.

A program for a liquid recovery system according to a seventh aspect of the present invention is a program for the liquid recovery system according to the sixth aspect, comprising:
The control process calculates an average daily amount of accumulated liquid by dividing a sum of amounts of liquid detected in the past by a corresponding number of days based on information on the amount of liquid detected by the detection device stored in the storage process;
This is a program for a liquid recovery system that calculates the number of remaining days by dividing the difference between the maximum allowable amount of the container and the amount of liquid by the average value.

The following describes an embodiment of the present invention with reference to the drawings.

As shown in FIG. 1, a liquid recovery system 10 according to an embodiment of the present invention includes:
A detection device 100 that detects the amount of liquid placed on a plurality of user sides;
A server 200 to which liquid amount information is transmitted from the detection device 100;
A first terminal 300 that is a terminal that can access the server 200;
A second terminal 400 which is a user terminal to which liquid amount information is transmitted from the detection device 100;
and a third terminal 500 that is a terminal that can access the server 200 and that enables the recovery staff to check the liquid during its movement for recovery.

Note that there may be multiple first terminals 300, second terminals 400, and third terminals 500, and the number is not limited.

The detection device 100 includes a container 110 for storing a liquid;
A liquid level sensor 120 for detecting the amount of liquid in the container 110;
A storage unit 130 that stores information on the amount of liquid detected by the liquid level sensor 120;
and a transmitting unit 140 that transmits information on the amount of liquid detected by the liquid level sensor 120 to the server 200.

The container 110 is a tank for storing liquid, and in this embodiment, it is a tank that can store 1000 L.

The liquid level sensor 120 is a sensor that detects the amount of liquid. In this embodiment, it uses an ultrasonic sensor to measure the distance to the liquid level and measures the amount of liquid from the height of the liquid level.

Specifically, the liquid level sensor 120 transmits high-frequency ultrasonic waves toward the liquid level in the container 110 and receives the high-frequency ultrasonic waves reflected by the liquid surface, and the ultrasonic transmission/reception unit 121 measures the time from transmission to reception of the high-frequency ultrasonic waves.

The liquid level sensor 120 then converts the time between transmission and reception of the high-frequency ultrasonic wave into distance and calculates the amount of liquid based on the capacity of the container 110.

The memory unit 130 stores information about the amount of liquid in the container 110 detected by the liquid level sensor 120.

The transmitter 140 transmits information about the amount of liquid detected by the liquid level sensor 120.

Specifically, the transmission unit 140 transmits information about the amount of liquid stored in the memory unit 130.

The information on the amount of liquid detected by the liquid level sensor 120 is transmitted by the transmission unit 140 to the server 200 and the second terminal 400, which is the user's terminal.

Information on the amount of liquid detected by the liquid level sensor 120 is sent to the server 200 and the second terminal 400, which is the user's terminal, at predetermined intervals.

The liquid level sensor 120 in this embodiment detects the amount of liquid in the container 110 once an hour and stores the amount in the memory unit 130.

In this embodiment, the information on the amount of liquid stored in the memory unit 130 is transmitted by the transmission unit 140 to the server 200 and the second terminal 400, which is the user's terminal, once every 13 hours.

In addition, the information on the amount of liquid sent to the second terminal 400 may not be sent directly from the detection device 100 to the second terminal 400, but may be sent only to the server 200.

The liquid quantity information may then be transmitted to the second terminal 400 from the server 200.

A repeater may also be provided between the transmission unit 140 and the server 200 or the second terminal 400.

The transmission method from the transmitting unit 140 to the server 200 or the second terminal 400 may be either wired or wireless.

In addition to Wi-Fi, short-range wireless communication such as Bluetooth (registered trademark) may also be used.

In this embodiment, the liquid level sensor 120 is used as the sensor of the detection device 100, but various other sensors such as a liquid level displacement sensor or a liquid volume sensor may also be used.

The server 200 includes a communication unit 210 that can communicate with the detection device 100, the first terminal 300, the second terminal 400, and the third terminal 500,
a mapping unit 220 that displays information on the amount of liquid received from the detection device 100 on a map displayed on the first terminal 300 and the third terminal;
a calendar unit 230 that displays information on the amount of liquid received from the detection device 100 on a calendar displayed on the first terminal 300 and the third terminal;
An alert unit 240 that notifies the user of a change in the amount of liquid;
A customer information management unit 250 that manages customer information;
A server storage unit 260 that stores liquid amount information, map information, list information, alert information, and customer information;
and a control unit 270 that predicts how the liquid will increase based on the history of the amount of liquid.

The server 200 may be made up of multiple servers, or may be a cloud server.

The communication unit 210 can communicate with the detection device 100 located on the user's side, the first terminal 300 for editing and displaying the information in the server 200, the second terminal 400 for displaying the amount of liquid by the detection device 100, and the third terminal 500 carried by the collection staff member for displaying the information in the server 200.

Communication by the communication unit 210 may be either wireless or wired.

The mapping unit 220 places the liquid quantity information received from each of the multiple detection devices 100 on a map 221.

The liquid quantity information received from the detection device 100 is stored in the server memory unit 260.

In addition, the map information of the map 221 displayed on the first terminal 300 and the third terminal 500 by the mapping unit 220 is stored in the server storage unit 260.

Figure 2 shows the display screens displayed on the first display unit 310 and the third display unit 510 of the first terminal 300 and the third terminal 500.

In the display screen shown in FIG. 2, the mapping unit 220 displays liquid quantity information on a map 221.

In this embodiment, the amount of liquid is expressed as a percentage or a number of liters corresponding to the percentage, and the location of each detection device 100 is located on the map 221.

The map 221 can be enlarged and reduced, and can also be changed to an aerial photograph, as shown in Figure 3.

By showing the position (location) of the detection device 100, i.e., the position (location) of the liquid container 110 on the map 221, and also the amount of liquid in the container 110, the user of the first terminal 300 and the user of the third terminal 500 (collection staff) can intuitively confirm where they should prioritize liquid collection.

The calendar unit 230 displays the liquid amount information received from the detection device 100 on a calendar displayed on the first terminal 300 and the third terminal 500.

The calendar unit 230 includes an amount prediction calendar 231 that displays the amount of liquid on a calendar displayed on the first terminal 300 and the third terminal 500;
and a collection schedule 232 for checking the liquid collection schedule.

The display screen shown in Figure 2 displays a quantity forecast calendar 231 and a collection schedule 232.

Figure 4 shows the display screen when the quantity forecast calendar 231 is selected, which is the "month" screen. Note that it can also be changed to the "week" screen.

In the quantity forecast calendar 231, customer information 231a, 231b, and 231c are displayed in such a way that customer information 231a with high urgency is displayed in red, customer information 231b with the next highest urgency is displayed in yellow, and regular customer information 231c is displayed in blue.

For example, the control unit 270 calculates (predicts) an estimated date when the amount of liquid will reach the maximum capacity of the container 110 based on the past amount of liquid (excrement) in the temporary toilet (changes in the amount of liquid in the past) and the capacity of the container 110.

Specifically, the control unit 270 predicts the number of days remaining until the liquid reaches the maximum allowable amount of the container 110, and determines the estimated date on which the liquid will reach the maximum allowable amount from the remaining number of days.

More specifically, the control unit 270 obtains the average amount of liquid per day by dividing the sum of the amounts of liquid detected in the past by the corresponding number of days, and calculates the number of days remaining until the liquid reaches the maximum allowable amount by dividing the difference between the total capacity of the container 110 and the amount of liquid in the container 110 by the average value.

For example, the control unit 270 divides the sum of the amount of liquid detected over 90 days by the number of days, 90, to obtain the average amount of liquid per day.

In other words, if the amount of liquid in the container 110 is 1800 L, the control unit 270 divides 1800 L by 90 days to find that the average amount of liquid per day is 20 L.

If the maximum allowable volume of the container 110 is 1000 L and the amount of liquid in the container 110 is 800 L, the control unit 270 will calculate the remaining number of days by dividing the difference between 1000 L and 800 L (200 L) by the average value of 20 L (10).

The calendar unit 230 displays customer information 231a, 231b, 231c on the quantity prediction calendar 231 on the day when the control unit 270 predicts that the liquid will reach the maximum capacity of the container 110.

The calendar section 230 sets two thresholds according to the amount of liquid in each portable toilet, and displays customer information on the amount prediction calendar 231 in blue (231c), yellow (231b), or red (231a) according to the thresholds.

Specifically, customer information is normally displayed in blue (231c) on the quantity prediction calendar 231, but if the amount of liquid detected by the detection device 100 is increasing (below the first threshold), it is displayed in yellow (231b), and if the amount of liquid detected by the detection device 100 is approaching the maximum allowable amount (below the second threshold), it is displayed in red (231a).

The threshold value can be set for each group. In this embodiment, when the amount of liquid falls below the first threshold, the color changes from blue to yellow, and when the amount falls below the second threshold, the color changes from yellow to red. However, the color can be any color as long as it can be distinguished. The threshold value can be set arbitrarily for each temporary toilet.

The quantity forecast calendar 231 displays "location of liquid," "type of liquid," and "amount of liquid" as customer information 231a, 231b, and 231c.

The quantity prediction calendar 231 displays customer information 231a, 231b, and 231c on the day before the liquid is predicted to run out of the container 110.

For example, the amount of liquid is displayed as a percentage of the amount of liquid and the amount divided by the total tank capacity (L), such as "7% 19.04/272L".

The customer information 231a (231b, 231c) displayed in Figures 5 and 6 is the display screen that appears when the customer information 231a (231b, 231c) displayed on the quantity forecast calendar 231 shown in Figure 4 is selected.

Figure 5 shows an example of a temporary toilet, where the liquid is waste material such as feces and urine. Figure 6 shows an example where the liquid is waste cooking oil.

Customer information 231a (231b, 231c) is stored in the server storage unit 260, and for example, as shown in Figures 5 and 6, customer information 231a (231b, 231c) includes customer name, address, location of container 110, type of liquid, type of container 110, amount used, tank capacity, status, signal level, number of days remaining, last collection date, serial number, temperature, amount of liquid, and estimated value.

As shown in Figures 5 and 6, the amount and estimated value of liquid (waste) are displayed on a graph.

For example, the customer information 231a (231b, 231c) shown in FIG. 5 shows that the remaining days are 1 day (October 21, 2021), and this customer information 231a (231b, 231c) is displayed in the position of October 21 on the quantity forecast calendar 231.

For example, the customer information 231a (231b, 231c) shown in FIG. 6 shows that the remaining days are 1 day (October 21, 2021), and this customer information 231a (231b, 231c) is displayed on the quantity forecast calendar 231 at October 21.

The liquid volume graph can be changed to display 1 week, 1 month, 3 months, 6 months, 12 months, etc.

The liquid volume graph also displays an estimate, which is a prediction of the liquid volume based on past changes in the graph.

In this embodiment, the estimated value is the quotient obtained by dividing the sum of past amounts by the number of days up to that point (converted into hours), and is the average amount per day.

The control unit 270 predicts the amount of liquid based on past changes in the amount of liquid (how it has increased) and the capacity of the container 110. Specific details will be described later.

When the schedule list 231d displayed on the quantity prediction calendar 231 is selected, a list of the "Installation location," "Type of liquid," and "Amount of liquid" displayed on the calendar is displayed.

Collection schedule 232 allows the liquid collection schedule to be confirmed, and is used by collection personnel to check their own collection schedules and by managers to check collection status, with the installation location being displayed on a calendar.

The alert unit 240 displays, among the multiple containers 110 on the map 221, the number of containers 110 in which the amount of liquid has increased and the number of containers 110 in which the amount of liquid has reached the maximum allowable amount.

In addition, the alert unit 240 issues warning information about the amount of liquid and a warning about malfunctions of the detection device 100 (e.g., mechanical malfunctions of the sensor, misalignment, etc.).

The alert unit 240 includes an alert display unit 241 that warns of the liquid status,
and an alert 242 that displays the specific content of the alert.

In the display screen shown in FIG. 2, the alert display section 241 and the alert 242 are displayed by the alert section 240.

The alert display unit 241 allows the user to check the number of containers 110 in which liquid has increased and the number of containers 110 in which the liquid has reached the maximum allowable amount.

When the Alert 242 page is opened, "Volume warning," "Sensor alert," and "Past warnings" are displayed on the screen, along with a list of "warnings" such as the "location" of the container 110 with the company name displayed, the "type" indicating the amount of liquid, and "The recovery level of XX is currently 21 and has exceeded the set threshold of 70% since 00:32:44 on 2021/10/4."

The customer information management unit 250 includes a customer 251 that displays customer information,
and a person in charge 252 that displays the person in charge of the customer.

Customer information is managed in the customer information management unit 250. Specifically, the customer name, postal code, address, telephone number, person in charge, the person in charge's email address, and mobile phone number are stored in the server storage unit 260, and the customer information management unit 250 manages this information.

Customer 251 displays customer information, including the customer's name, postal code, address, phone number, and contact person.

Person in charge 252 displays the customer's person in charge and their email address. Person in charge 252 may also display the mobile phone number of the customer's person in charge.

The server memory unit 260 stores liquid quantity information from each detection device 100.

The server storage unit 260 also stores customer information, map information, list information, and alert information.

The server memory unit 260 stores, for example, a reference amount (numerical value) for determining the amount information, the capacity of the container 110 installed at each installation location, the standard increase in the amount of liquid at each installation location, the date and time when the liquid was last collected at each installation location, and the address of each installation location.

The customer information is the same as the customer information 231a. The map information is the map information of the map 221 displayed on the first terminal 300 and the third terminal 500.

List information is information displayed in a list on the quantity forecast calendar 231.

Alert information is information displayed on the alert unit 240, such as information displayed when the liquid exceeds a threshold value, or information displayed when an abnormality occurs in the detection device 100.

For example, if a mechanical malfunction occurs in the liquid level sensor 120 or if the sensor is positioned at an angle for some reason, this is displayed and stored as alert information.

The control unit 270 predicts how the liquid will increase in the container 110 based on changes in the liquid quantity information stored in the server memory unit 260.

Specifically, the control unit 270 calculates the average hourly change in the amount of liquid in the container 110 thus far, which is stored in the server storage unit 260.

More specifically, the control unit 270 predicts the number of days remaining until the liquid reaches the maximum allowable amount of the container 110, and determines the estimated date on which the liquid will reach the maximum allowable amount from the number of days remaining.

The number of days remaining until the liquid reaches the maximum allowable amount is calculated and determined by the control unit 270 as described above.

The control unit 270 may also calculate the average hourly change in the amount of liquid in the container 110 stored in the server memory unit 260 to date, and calculate the estimated day on which the liquid in the container 110 will reach the maximum allowable amount.

The estimated date when the liquid will reach its maximum allowable volume is displayed on the volume forecast calendar 231.

The server 200 may store quantity information and current location information of the delivery vehicle via electrical communication circuits.

The liquid recovery system 10 of this embodiment can recover liquid in units of, for example, 1 liter.

In other words, in this embodiment, recovery can be performed before the container 110 reaches its maximum capacity.

For example, the control unit 270 can set a collection group based on the installation location information (customer information 231a, 231b, 231c) stored in the server storage unit 260 as follows:

Installation location information refers to customer information 231a, 231b, and 231c, such as the address of the temporary toilet (installation location), information on the amount of liquid in each temporary toilet, the tank capacity of the container 110 in each temporary toilet (installation location), and the history of the amount of liquid in each temporary toilet (installation location).

As shown in Figures 5 and 6, liquid volume history is a record of past amounts of liquid, and is stored in the server storage unit 260.

The collection group can be set, for example, based on the address of the temporary toilet (installation location) to include nearby temporary toilets (installation locations) or temporary toilets (installation locations) in the same direction as the collection source (location of the collection company).

For example, if a recovery company (a user of the liquid recovery system 10 according to this embodiment) is located in Kyoto Prefecture, collection locations in Shiga Prefecture and Fukui Prefecture can be set as the same collection group, and collection locations in Osaka Prefecture and Hyogo Prefecture can be set as the same collection group.

In addition, if the location of the collection company (the user of the liquid collection system 10 according to this embodiment) is in Kyoto City, the collection location in Uji City, Kyoto Prefecture and the collection location in Joyo City, Kyoto Prefecture (both located south of the location of the collection company in Kyoto City) can be set as the same collection group, and the collection location in Maizuru City, Kyoto Prefecture and the collection location in Fukuchiyama City, Kyoto Prefecture (both located north of the location of the collection company in Kyoto City) can be set as the same collection group.

The collection group is set to include, with priority, customer information 231a with high urgency that is displayed on the quantity forecast calendar 231.

The collection group may be set by the person in charge at the collection company, or the control unit 270 may set the collection group.

In addition, in this embodiment, the liquid is waste material such as feces and urine and waste edible oil, but it may also be waste oil, waste liquid, sewage, or sludge.

The present invention can be implemented in various forms with various improvements, modifications, or variations without departing from the spirit of the invention.
